The scientific name for Ammobroma is Pholisma sonorae--it was originally named Ammobroma sonorae, but it is now thought to belong to the genus Pholisma. Pholisma was said to be in the small family of parasitic plants Lennoaceae, but now Lennoaceae is considered a subfamily (Lennoideae) of Boraginaceae, the forget-me-not family. This is a smaller inflorescence, which looks doughnut-like in shape, but is actually funnel-shaped, the outer edges of the funnel rounded, and the center of the funnel filled with sand.
